# A Simple Symmetries Theorems for 3d N=4 Theories

Comments: 12 pages, 4 figures

We show that a simple symmetries theorem for 3d N=4 theories is a consequence of a 2d gauge theory which satisfies the first law for the gauge group of the Minkowski spacetime. It is shown that this theorem is equivalent to the Lie-polynomial theorem and that it is a consequence of the standard (2d) and (3d) symmetries theorem for 3d gauge theories.
